ところで、上記従来技術に係るモータにおいて、結線用部材を介してバスリングにステータコイルを接続する際には、結線用部材とバスリングの端子部および結線用部材とステータコイルの周方向の２箇所においてヒュージングを行う必要があり、このヒュージングの作業に要する作業空間が増大することから、例えばモータの径方向寸法を増大させずに、極対数を増大させることが困難となり、モータに対する空間的な設計の自由度が低下してしまうという問題が生じる。しかも、バスリングに複数のＵ字状に湾曲する端子部を設けることから、これらの端子部を収容するための空間が必要となり、モータが大型化してしまうという問題が生じる。
また、上記従来技術に係るモータの集中配電部材においては、３相のバスバーを保持するために複数（３種類）の異なるクリップを用いることから、構成に必要とされる部品点数および費用が嵩み、集中配電部材を構成する工程に煩雑な手間がかかるという問題が生じる。

Since the working space required for this fusing work increases, for example, it becomes difficult to increase the number of pole pairs without increasing the radial dimension of the motor. This causes a problem that the degree of freedom of design is reduced. In addition, since the bus ring is provided with a plurality of U-shaped terminal portions, a space for accommodating these terminal portions is required, resulting in a problem that the motor is increased in size.
Moreover, in the concentrated power distribution member of the motor according to the above prior art, since a plurality of (three types) different clips are used to hold the three-phase bus bar, the number of parts and cost required for the configuration increase. As a result, there is a problem that the process of forming the centralized power distribution member takes a complicated time.
The present invention has been made in view of the above circumstances, and it is possible to appropriately reduce the size of the rotating electrical machine while ensuring a desired output, to reduce the number of parts and cost required for the configuration, and to make the configuration process complicated. It is an object of the present invention to provide a power collection and distribution ring for a rotating electrical machine that can prevent troubles.

上記課題を解決して係る目的を達成するために、本発明の第１態様に係る回転電機の集配電リングは、複数相のモータの各相毎に同一相のコイル（例えば、実施の形態でのステータコイル３４）を接続する複数相のバスリング（例えば、実施の形態でのバスリング４１Ｕ，４１Ｖ，４１Ｗ）と、前記複数相の前記バスリングの所定周方向位置で前記複数相の前記バスリングに固定される複数の固定部材（例えば、実施の形態での固定部材４５，…，４５）と、前記複数相の前記バスリングの周方向の所定位置に固定されて前記コイルの引出し線部（例えば、実施の形態での引き出し線部３４ａ）と接続可能な接続端子（例えば、実施の形態での接続端子４４）とを備え、前記コイルを保持する絶縁部材は、前記コイルの引出し線部を位置決め固定する保持部材（例えば、実施の形態での位置決め部材５１）を備え、前記接続端子は、前記バスリングに固定されたバスリング固定部（例えば、実施の形態でのバスリング固定部４４ａ）と、前記バスリング固定部から径方向内方に延出する延出部（例えば、実施の形態での延出湾曲部４４ｂ）と、前記延出部の先端において前記コイルの前記引出し線部と接続されるコイル接続部とを備え、前記バスリング固定部と前記コイル接続部とは周方向で重複するように配置され、前記延出部は、前記バスリング固定部と前記コイル接続部との間に配置される前記保持部材を迂回する迂回部（例えば、実施の形態での延出湾曲部４４ｂ）を備える。 In order to solve the above-described problems and achieve the object, the power collection and distribution ring of the rotating electrical machine according to the first aspect of the present invention includes a coil of the same phase for each phase of a motor of a plurality of phases (for example, in the embodiment).

An extended portion (for example, an extended curved portion 44b in the embodiment) extending radially inward from the bus ring fixing portion, and connected to the lead wire portion of the coil at the tip of the extended portion The bus ring fixing portion and the coil connecting portion are arranged so as to overlap in the circumferential direction, and the extending portion is between the bus ring fixing portion and the coil connecting portion. A detouring part (for example, the extended curved part 44b in the embodiment) that detours the holding member disposed in the position is provided.

さらに、本発明の第２態様に係る回転電機の集配電リングでは、前記保持部材は、前記バスリングの周方向を基準として、前記絶縁部材の中心軸の周方向位置から周方向にずれた位置に配置されている。 Furthermore, in the power distribution ring of the rotating electrical machine according to the second aspect of the present invention, the holding member is shifted in the circumferential direction from the circumferential position of the central axis of the insulating member with respect to the circumferential direction of the bus ring.

The coil and the coil connecting portion are connected by fusing after the bus ring is mounted in the power collection and distribution member accommodating portion.

第１態様に係る回転電機の集配電リングによれば、コイルの引出し線部と接続可能な接続端子は、予めバスリングの所定位置に固定されていることから、各コイルの引出し線部と接続端子との間のヒュージング（熱かしめ）などによる１回の接続作業のみで、各コイルを接続端子を介してバスリングに容易に接続することができ、この接続作業に要する作業空間が過剰に増大することを防止しつつ、回転電機に対する空間的な設計の自由度が低下してしまうことを防止することができ、構成に要する部品点数および費用を削減し、構成の工程に煩雑な手間がかかることを防止することができる。

Even when edgewise bending is required, it is possible to prevent the winding material from being disturbed.

さらに、第４態様に係る回転電機の集配電リングによれば、接続端子と固定部材とは周方向で重複しないように配置されていることから、樹脂材によるモールド加工に必要とされる所望の作業空間を適切に確保することができる。 Furthermore, according to the power collection and distribution ring of the rotating electrical machine according to the fourth aspect, since the connection terminal and the fixing member are arranged so as not to overlap in the circumferential direction, the desired processing required for molding with the resin material is performed. A work space can be appropriately secured.

Further, the power collecting / distributing member 13 is accommodated in the power collecting / distributing member accommodating portion 32b, and the midpoint connecting member 14 is accommodated in the midpoint connecting member accommodating portion 32c.

集配電部材１３は、例えば複数相（例えば、Ｕ相、Ｖ相、Ｗ相の３相）の各相毎に複数のステータコイル３４，…，３４を接続する複数相の環状のバスリング４１Ｕ，４１Ｖ，４１Ｗを備え、複数相の各相毎のバスリング４１Ｕ，４１Ｖ，４１Ｗは、互いに略同等形状を有し、円環状のリードフレーム４２と、このリードフレーム４２に設けられた給電端子４３と、リードフレーム４２の周方向所定位置（つまり、周方向の所定間隔毎の位置）に固定されて径方向内方に突出し、各複数のステータコイル３４と接続される複数の接続端子４４，…，４４と、複数相の環状のバスリング４１Ｕ，４１Ｖ，４１Ｗの所定周方向位置で装着されて複数相のバスリング４１Ｕ，４１Ｖ，４１Ｗを固定する複数の同一形状の固定部材４５，…，４５と、各バスリング４１Ｕ，４１Ｖ，４１Ｗの給電端子４３近傍の部位を固定する端子部固定部材４６とを備えて構成されている。
なお、各相毎のバスリング４１Ｕ，４１Ｖ，４１Ｗに対して、各相同士のリードフレーム４２および固定部材４５および端子部固定部材４６は同等形状とされている。また、各相同士の給電端子４３では、各相毎のバスリング４１Ｕ，４１Ｖ，４１Ｗが軸方向の他方から一方に向かい、順次、同軸に積層された状態での軸方向位置の差異を補償するようにして、軸方向長さが各相毎に異なる値に設定されている。 The current collecting and distributing member 13 includes, for example, a plurality of annular bus rings 41U, which connect a plurality of stator coils 34,... The bus rings 41U, 41V, 41W for each of a plurality of phases have substantially the same shape, and have an annular lead frame 42 and a power supply terminal 43 provided on the lead frame 42. , A plurality of connection terminals 44,..., Fixed at predetermined positions in the circumferential direction of the lead frame 42 (that is, positions at predetermined intervals in the circumferential direction) and projecting inward in the radial direction and connected to the plurality of stator coils 34. 44, and a plurality of fixing members 45,..., 45 of the same shape that are mounted at predetermined circumferential positions of the plurality of annular bus rings 41U, 41V, 41W and fix the plurality of bus rings 41U, 41V, 41W. , Bus rings 41U, 41V, and is constituted by a terminal portion fixing member 46 for fixing the site of the power supply terminals 43 near the 41W.
In addition, with respect to the bus rings 41U, 41V, and 41W for each phase, the lead frame 42, the fixing member 45, and the terminal portion fixing member 46 for each phase have the same shape. Further, in the power supply terminals 43 of the respective phases, the bus rings 41U, 41V, 41W for the respective phases are directed from the other axial direction to the other to compensate for the difference in the axial position in the state where they are sequentially coaxially stacked. Thus, the axial length is set to a different value for each phase.

環状のリードフレーム４２は、絶縁被覆（図示略）を有する導線が円環状に成形され、導線の一端部および他端部が径方向外方に突出すると共に軸方向一方側に向かい屈曲した状態で給電端子４３に接続されて構成されている。
さらに、リードフレーム４２の周方向所定位置（つまり、周方向の所定間隔毎の位置）には、絶縁被覆（図示略）が剥がされて導線本体が露出した部位（露出部４２ａ）が設けられ、この露出部４２ａに接続端子４４のバスリング固定部４４ａが、例えばヒュージング（熱かしめ）などにより接続固定されている。 In the annular lead frame 42, a conducting wire having an insulating coating (not shown) is formed in an annular shape, and one end and the other end of the conducting wire protrude radially outward and are bent toward one side in the axial direction. It is configured to be connected to a power supply terminal 43.
Furthermore, at a predetermined position in the circumferential direction of the lead frame 42 (that is, a position at a predetermined interval in the circumferential direction), a portion (exposed portion 42a) where the insulating coating (not shown) is removed and the conductor body is exposed is provided. The bus ring fixing portion 44a of the connection terminal 44 is connected and fixed to the exposed portion 42a by, for example, fusing (heat caulking).

接続端子４４は、例えば図２から図６に示すように、リードフレーム４２の露出部４２ａに固定されるバスリング固定部４４ａと、バスリング固定部４４ａから径方向内方に向かい延出すると共に、集配電部材収容部３２ｂ内に設けられた位置決め部材５１を迂回するようにして周方向の他方側に向かい湾曲する延出湾曲部４４ｂと、延出湾曲部４４ｂの径方向内方側の端部において軸方向に向かい略Ｕ字状に湾曲するコイル接続部４４ｃとを備えて構成されている。そして、集配電部材収容部３２ｂに集配電部材１３が収容された状態でバスリング固定部４４ａとコイル接続部４４ｃとの周方向位置が重複するように設定されている。
なお、接続端子４４では、各相毎のバスリング４１Ｕ，４１Ｖ，４１Ｗが軸方向の他方から一方に向かい、順次、同軸に積層された状態での軸方向位置の差異を補償するようにして、バスリング固定部４４ａおよびコイル接続部４４ｃの形状が設定されている。つまり、接続端子４４のコイル接続部４４ｃは、例えばヒュージング（熱かしめ）等によりステータコイル３４の一端からなる引き出し線部３４ａに接続されていることから、各相毎のバスリング４１Ｕ，４１Ｖ，４１Ｗに設けられた各接続端子４４のコイル接続部４４ｃは軸方向位置（つまり、軸方向での引き出し線部３４ａとの接続位置）が同一とされ、この各コイル接続部４４ｃの軸方向位置に対して、各相毎のバスリング４１Ｕ，４１Ｖ，４１Ｗに設けられた各接続端子４４の各バスリング固定部４４ａの軸方向位置は互いに異なることから、各バスリング固定部４４ａとコイル接続部４４ｃとの間の延出湾曲部４４ｂも各相毎のバスリング４１Ｕ，４１Ｖ，４１Ｗに応じて互いに異なる形状となる。 As shown in FIGS. 2 to 6, for example, the connection terminal 44 is a bus ring fixing portion 44 a fixed to the exposed portion 42 a of the lead frame 42, and extends radially inward from the bus ring fixing portion 44 a. An extended curved portion 44b that curves toward the other side in the circumferential direction so as to bypass the positioning member 51 provided in the current collecting and distributing member accommodating portion 32b, and a radially inner end of the extended curved portion 44b And a coil connecting portion 44c that is curved in a substantially U shape in the axial direction. Then, the circumferential positions of the bus ring fixing portion 44a and the coil connecting portion 44c are set to overlap in a state where the power collecting / distributing member 13 is accommodated in the power collecting / distributing member accommodating portion 32b.
In the connection terminal 44, the bus rings 41U, 41V, 41W for each phase are directed from the other axial direction to the other, so as to compensate for the difference in the axial position in a state where they are sequentially coaxially stacked. The shapes of the bus ring fixing part 44a and the coil connection part 44c are set. That is, since the coil connection portion 44c of the connection terminal 44 is connected to the lead wire portion 34a formed from one end of the stator coil 34 by, for example, fusing (heat caulking) or the like, the bus rings 41U, 41V, The coil connection portions 44c of the connection terminals 44 provided in 41W have the same axial position (that is, the connection position with the lead wire portion 34a in the axial direction), and the coil connection portions 44c are positioned at the axial positions of the coil connection portions 44c. On the other hand, since the axial positions of the bus ring fixing portions 44a of the connection terminals 44 provided on the bus rings 41U, 41V, 41W for the respective phases are different from each other, the bus ring fixing portions 44a and the coil connection portions 44c are different from each other.

At the circumferential position that overlaps with the circumferential position of the terminal 44, that is, at the end portion on one side in the circumferential direction of the power collection and distribution member accommodating portion 32b, the outer peripheral portion is cut out to provide a cutout portion 53. The cutout portion 53 is provided at a position on the radially outer side of the lead wire portion 34 a that is positioned by the positioning member 51 and is drawn radially outward from the stator coil 34, and the stator coil 34 is formed by a conducting wire. In this case, since the conducting wire is wound around the bobbin portion of the insulating bobbin 32 and drawn out to the radially outward side with a desired tension, the conducting wire drawn out to the radially outward side has a predetermined position in the radial direction. When the lead wire portion 34a is formed by cutting the wire, a lead wire cutting tool (not shown) is required to be disposed at a predetermined radial position.

端子部固定部材４６は、各相毎のバスリング４１Ｕ，４１Ｖ，４１Ｗが軸方向の他方から一方に向かい、順次、同軸に積層された状態で、これらのバスリング４１Ｕ，４１Ｖ，４１Ｗの各リードフレーム４２の給電端子４３近傍の部位を被覆する電気的絶縁性の樹脂材によるモールド加工によって形成されている。
端子部固定部材４６は、固定部材４５と同様に、集配電部材収容部３２ｂの外周壁部５２に設けられた穴部５２ａに装着可能とされて、集配電部材１３が集配電部材収容部３２ｂ内に収容された状態で外周壁部５２の穴部５２ａを閉塞する突出部４６ａを備えている。
これにより、集配電部材収容部３２ｂ内においてバスリング４１Ｕ，４１Ｖ，４１Ｗおよび引き出し線部３４ａの周囲に絶縁剤を充填するための閉塞空間を固定部材４５および端子部固定部材４６および外周壁部５２によって形成することができる。 The terminal portion fixing member 46 is configured so that the bus rings 41U, 41V, 41W for the respective phases are directed from the other side to the other side in the axial direction, and are sequentially stacked coaxially. The frame 42 is formed by molding with an electrically insulating resin material that covers the vicinity of the power supply terminal 43 of the frame 42.
Similarly to the fixing member 45, the terminal fixing member 46 can be mounted in the hole 52a provided in the outer peripheral wall portion 52 of the power collecting / distributing member accommodating portion 32b, and the power collecting / distributing member 13 is connected to the power collecting / distributing member accommodating portion 32b. The protrusion 46a which obstruct | occludes the hole 52a of the outer peripheral wall part 52 in the state accommodated in the inside is provided.
As a result, the closed space for filling the insulating material around the bus rings 41U, 41V, 41W and the lead wire portion 34a in the power collection / distribution member accommodating portion 32b becomes the fixing member 45, the terminal portion fixing member 46, and the outer peripheral wall portion 52. Can be formed.

各相毎のバスリング４１Ｕ，４１Ｖ，４１Ｗは、軸方向の他方から一方に向かい、順次、同軸に積層されると共に周方向に所定角度づつずれた状態で複数の固定部材４５，…，４５によって固定され、各相毎のバスリング４１Ｕ，４１Ｖ，４１Ｗの各リードフレーム４２，４２，４２に固定された各接続端子４４，４４，４４が、順次、周方向で所定間隔毎に隣り合うように配置されている   The bus rings 41U, 41V, and 41W for each phase are sequentially stacked coaxially from the other axial direction to one side, and are shifted by a plurality of fixing members 45,. The connection terminals 44, 44, 44 fixed and fixed to the lead frames 42, 42, 42 of the bus rings 41U, 41V, 41W for each phase are sequentially adjacent to each other at predetermined intervals in the circumferential direction. Arranged

そして、各相のバスリング４１Ｕ，４１Ｖ，４１Ｗと対応する相の各ステータ片１２ａの各ステータコイル３４同士が接続され、Ｕ相の各ステータ片１２ａのステータコイル３４の一端からなる引き出し線部３４ａ同士はバスリング４１Ｕを介して接続され、Ｖ相の各ステータ片１２ａのステータコイル３４の一端からなる引き出し線部３４ａ同士はバスリング４１Ｖを介して接続され、Ｗ相の各ステータ片１２ａのステータコイル３４の一端からなる引き出し線部３４ａ同士はバスリング４１Ｗを介して接続される。   The stator coils 34 of the stator pieces 12a of the phases corresponding to the bus rings 41U, 41V, 41W of the phases are connected to each other, and a lead wire portion 34a including one end of the stator coil 34 of the stator pieces 12a of the U phase. They are connected to each other via a bus ring 41U, and lead wire portions 34a composed of one end of the stator coil 34 of each V-phase stator piece 12a are connected to each other via a bus ring 41V, and the stator of each W-phase stator piece 12a. The lead wire portions 34a formed from one end of the coil 34 are connected to each other via a bus ring 41W.

なお、中点連結部材１４は、例えば図１に示すように、周方向で隣り合うステータ片１２ａ，１２ａの各ステータコイル３４の他端同士を、例えばヒュージング（熱かしめ）などにより接続する接続部材１４ａを備え、総ての相のステータ片１２ａ，…，１２ａのステータコイル３４，…，３４の他端同士を接続している。そして、中点連結部材１４が収容された中点連結部材収容部３２ｃ内には絶縁性の樹脂材（図示略）が充填されている。   For example, as shown in FIG. 1, the midpoint connecting member 14 is a connection that connects the other ends of the stator coils 34 of the stator pieces 12 a and 12 a adjacent to each other in the circumferential direction by, for example, fusing (heat caulking). A member 14a is provided, and the other ends of the stator coils 34,..., 34 of the stator pieces 12a,. An insulating resin material (not shown) is filled in the midpoint connecting member housing portion 32c in which the midpoint connecting member 14 is housed.

上述したように、この実施の形態による回転電機の集配電リングによれば、固定部材４５および端子部固定部材４６により固定された複数相の環状のバスリング４１Ｕ，４１Ｖ，４１Ｗにおいて、予め、各リードフレーム４２の露出部４２ａには接続端子４４が固定されていることから、固定部材４５および端子部固定部材４６により固定された複数相の環状のバスリング４１Ｕ，４１Ｖ，４１Ｗが集配電部材収容部３２ｂ内に装着された際には、各ステータコイル３４の引出し線部３４ａと接続端子４４との間のヒュージング（熱かしめ）などによる１回の接続作業のみで、各リードフレーム４２とステータコイル３４とが接続端子４４を介して容易に接続されることになり、この接続作業に要する作業空間（例えば、図５に示す作業空間α）が集配電部材収容部３２ｂ内において過剰に増大することを防止しつつ、回転電機に対する空間的な設計の自由度が低下してしまうことを防止することができ、構成に要する部品点数および費用を削減し、構成の工程に煩雑な手間がかかることを防止することができる。   As described above, according to the power collection and distribution ring of the rotating electrical machine according to this embodiment, in each of the multiple-phase annular bus rings 41U, 41V, and 41W fixed by the fixing member 45 and the terminal portion fixing member 46, Since the connection terminal 44 is fixed to the exposed portion 42a of the lead frame 42, the multiple-phase annular bus rings 41U, 41V, and 41W fixed by the fixing member 45 and the terminal portion fixing member 46 are accommodated in the power collection and distribution member. When mounted in the portion 32b, each lead frame 42 and the stator can be connected with only one connection work by fusing (heat caulking) between the lead wire portion 34a of each stator coil 34 and the connection terminal 44. The coil 34 is easily connected via the connection terminal 44, and a work space required for this connection work (for example, the work space shown in FIG. 5). ) Can be prevented from excessively increasing in the current collection / distribution member housing portion 32b, and the spatial design freedom for the rotating electrical machine can be prevented from being reduced, and the number of parts and cost required for the configuration can be reduced. It is possible to prevent a troublesome labor in the configuration process.

一方、例えば図１０および図１１に示す上述した実施の形態の比較例の集配電部材８１のように、集中巻きの複数のステータコイル３４の径方向外方に設けられた集配電部材８１において、各相のリードフレーム８２から径方向内方に突出してＵ字状に湾曲する端子部８３に対して、周方向で隣り合うようにしてＵ字状の結線用部材８４を配置し、端子部８３の周方向一端部（つまり、絶縁被覆（図示略）が剥がされてリードフレーム本体が露出した部位）８３ａと結線用部材８４の周方向他端部８４ａとをヒュージングにより接続し、結線用部材８４の周方向一端部８４ｂにステータコイル３４の引き出し線部３４ａをヒュージングにより接続する場合には、集配電部材８１をステータコイル３４の径方向外方に配置した状態でステータコイル３４と各相のリードフレーム８２とを接続する際に２回のヒュージング（熱かしめ）が必要となり、このヒュージングの作業に要する集配電部材収容部３２ｂ内の作業空間（例えば、図９に示す作業空間β）が増大すると共に、端子部８３および結線用部材８４を収容するための相対的に大きな空間が必要となり、この集配電部材８１を備える回転電機が大型化してしまったり、回転電機の径方向寸法を増大させずに、極対数を増大させることが困難となり、回転電機に対する空間的な設計の自由度が低下してしまうという問題が生じる。
これに対して、本発明の実施の形態によれば、リードフレーム４２に予め接続端子４４が接続されるだけであるから、接続端子４４を収容するための相対的に小さな空間を要するだけであり、回転電機の径方向寸法の増大を抑制しつつ、回転電機の極対数を容易に増大させることができる。 On the other hand, in the current collection and distribution member 81 provided radially outward of the plurality of concentrated winding stator coils 34, for example, as in the comparative example of the current collection and distribution member 81 of the above-described embodiment shown in FIG. 10 and FIG. A U-shaped connecting member 84 is arranged so as to be adjacent in the circumferential direction to a terminal portion 83 that protrudes inward in the radial direction from the lead frame 82 of each phase and curves in a U shape. One end portion in the circumferential direction (that is, the portion where the insulation coating (not shown) is peeled off and the lead frame main body is exposed) 83a and the other circumferential end portion 84a of the connection member 84 are connected by fusing, and the connection member 84, when the lead wire portion 34a of the stator coil 34 is connected to the circumferential end 84b by fusing, the stator coil is disposed in a state in which the current collection and distribution member 81 is disposed radially outward of the stator coil 34. When connecting the lead 34 and the lead frame 82 of each phase, two fusings (heat caulking) are required, and a work space (for example, FIG. 9) in the power collecting / distributing member housing portion 32b required for the fusing work is required. And a relatively large space for accommodating the terminal portion 83 and the connection member 84 is required, and the rotating electrical machine including the current collecting and distributing member 81 is increased in size or rotated. Without increasing the radial dimension of the electric machine, it becomes difficult to increase the number of pole pairs, resulting in a problem that the degree of freedom in spatial design for the rotating electric machine is reduced.
On the other hand, according to the embodiment of the present invention, since the connection terminal 44 is only connected to the lead frame 42 in advance, only a relatively small space for accommodating the connection terminal 44 is required. It is possible to easily increase the number of pole pairs of the rotating electrical machine while suppressing an increase in the radial dimension of the rotating electrical machine.

また、接続端子４４と固定部材４５および端子部固定部材４６とは周方向で重複しないように配置されていることから、樹脂材によるモールド加工に必要とされる所望の作業空間を適切に確保することができる。
さらに、引き出し線部３４ａを位置決め固定しつつ接続端子４４のコイル接続部４４ｄに導く位置決め部材５１を集配電部材収容部３２ｂに設けることから、ステータコイル３４の引出し線部３４ａの位置決め精度を向上させることができる。
しかも、位置決め部材５１をステータコイル３４の中心軸の周方向位置から周方向の一方側（つまり絶縁ボビン３２のボビン部に巻回される導線の巻回方向）にずれた位置に設けることで、ステータコイル３４から径方向外方に引き出し線部３４ａを引き出す際に適切に曲げ加工をおこなうことができ、例えば平角線にエッジワイズ曲げが必要とされる場合などであっても導線の巻き乱れの発生を防止することができる。 Further, since the connection terminal 44, the fixing member 45, and the terminal portion fixing member 46 are arranged so as not to overlap in the circumferential direction, a desired work space required for molding with a resin material is appropriately ensured. be able to.
Further, since the positioning member 51 that guides the coil connection portion 44d of the connection terminal 44 while positioning and fixing the lead wire portion 34a is provided in the current collection and distribution member accommodating portion 32b, the positioning accuracy of the lead wire portion 34a of the stator coil 34 is improved. be able to.
Moreover, by providing the positioning member 51 at a position shifted from the circumferential position of the central axis of the stator coil 34 to one side in the circumferential direction (that is, the winding direction of the conducting wire wound around the bobbin portion of the insulating bobbin 32), Bending can be appropriately performed when the lead wire portion 34a is pulled out from the stator coil 34 in the radial direction. For example, even when edgewise bending is required for a flat wire, the winding of the conductor is not disturbed. Occurrence can be prevented.

さらに、接続端子４４は、周方向で重複するように配置されるバスリング固定部４４ａおよびコイル接続部４４ｃと、集配電部材収容部３２ｂ内に設けられた位置決め部材５１を迂回するようにして周方向の他方側に向かい湾曲する延出湾曲部４４ｂとを備えることから、集配電部材収容部３２ｂ内において接続端子４４が過剰に大きくなることを防止して、回転電機に対する空間的な設計の自由度が低下してしまうことを防止することができる。   Further, the connection terminal 44 circumvents the bus ring fixing portion 44a and the coil connection portion 44c, which are arranged so as to overlap in the circumferential direction, and the positioning member 51 provided in the current collection and distribution member accommodating portion 32b. And an extended curved portion 44b that curves toward the other side of the direction, so that the connection terminal 44 is prevented from becoming excessively large in the current collecting and distributing member accommodating portion 32b, and the spatial design freedom for the rotating electrical machine is free. It is possible to prevent the degree from decreasing.
